Product details
Overview
XC4004A-6TQ144I from Xilinx is a 5 V, speed-grade -6 Field-Programmable Gate Array (FPGA) in the XC4000E family, featuring 4,000 usable logic gates, 144-pin TQFP package, synchronous SelectRAM™ memory, and IEEE 1149.1 boundary-scan support - deployed in legacy PCI-compliant interface controllers and industrial control logic.
For engineers reviewing the XC4004A-6TQ144I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, CLB-level timing behavior, I/O buffer configuration options, and pin-compatible alternatives for obsolescence-mitigated re-designs.
Technical Context
The XC4004A-6TQ144I implements a regular array of Configurable Logic Blocks (CLBs), each containing dual 4-input function generators (F/G), a 3-input H generator, two edge-triggered D-type flip-flops, and configurable RAM modes (16×2, 32×1, or 16×1 dual-port). It uses a sub-micron CMOS process with hierarchical routing and eight global low-skew clock networks.
Its IOBs support individually programmable slew rate, 5 V-tolerant inputs, TTL/CMOS input threshold selection, and soft start-up to suppress ground bounce. Configuration occurs via master serial, slave serial, or master parallel modes using external PROMs or host processors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 4,000 usable gates (typical gate range: 2,000–5,000 with RAM usage) |
| CLB Count | 100 CLBs arranged in 10×10 matrix - defines maximum combinational depth and register count |
| Max User I/O | 80 pins - supports full peripheral interfacing without external glue logic |
| System Clock Rate | Up to 80 MHz (speed grade -6 guarantees timing closure at this frequency) |
| SelectRAM™ Modes | Edge-triggered write + dual-port read/write - enables synchronous FIFOs with zero external latency |
| I/O Sink Current | 12 mA per output - drives standard TTL loads directly without buffers |
| Configuration Mode | Master Serial / Slave Serial / Master Parallel - determines boot source and address width (18-bit for XC4004A) |
Pinout & Package
XC4004A-6TQ144I is housed in a 144-pin Thin Quad Flat Package (TQFP), 20 mm × 20 mm, 0.5 mm pitch, with 80 user I/O pins, 8 global clock/network pins, 4 dedicated configuration pins (PROGRAM, INIT, CCLK, DONE), and power/ground distribution across all four sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK7 | Global Clock Input | Low-skew dedicated clock network inputs - drive all CLBs and IOBs simultaneously |
| IO_Lxx | User I/O Buffer | Configurable as input, output, or bidirectional with programmable pull-up/down and slew rate |
| PROGRAM | Configuration Reset | Active-low asynchronous reset that clears configuration memory and initiates reload sequence |
| INIT | Configuration Status | Open-drain output indicating successful configuration completion or error condition |
| CCLK | Configuration Clock | Input clock for serial configuration mode - controls bitstream shift-in timing |
| DONE | Configuration Completion | Output signal confirming internal configuration registers are loaded and device is operational |
Key Features
| Feature | Design Value |
|---|---|
| SelectRAM™ Memory | On-chip synchronous RAM per CLB - eliminates external SRAM for control state storage and small buffers |
| IEEE 1149.1 Boundary Scan | Fully compliant JTAG test access - enables board-level interconnect verification without physical probes |
| Dual-Port RAM Option | 16×1 dual-port mode per CLB - allows simultaneous read/write to same memory location for pipelined data flow |
| Programmable Slew Rate | Per-IOB control - reduces EMI and signal integrity issues in mixed-signal PCB layouts |
| Soft Start-up | Automatic slew-rate limiting on power-up - prevents ground bounce during simultaneous output activation |
| Backward Compatibility | Pinout- and bitstream-compatible with XC4004 - enables drop-in replacement in existing XC4000 designs |
Applications
| PCI Interface Controller | Industrial Motion Control |
|---|---|

Use Value: On-chip SelectRAM™ stores 16k-bit patterns; synchronous write mode ensures deterministic vector launch aligned to system clock edge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4004E-6TQ144I | Same pinout and package; enhanced routing resources and additional carry logic - not bitstream-compatible with XC4004A | Supports larger designs requiring higher interconnect density; lacks backward compatibility with original XC4000 bitstreams | Select when migrating from XC4004A to gain routing flexibility without changing PCB layout. |
| XC4005E-6TQ144C | 144-pin TQFP, 5,000-gate capacity, -6 speed grade, commercial temperature range - identical I/O structure but higher gate count | Suitable for designs needing margin in logic utilization or future feature expansion without footprint change | Choose for new designs where gate headroom is required and extended temperature operation is not mandatory. |
Compared with XC4004A-6TQ144I, XC4004E-6TQ144I offers improved routing but requires recompilation, while XC4005E-6TQ144C provides extra logic capacity within the same package - both preserve mechanical and electrical interface compatibility for seamless integration into legacy 144-pin TQFP footprints.

FAQ
Is XC4004A-6TQ144I still in production?
No - XC4004A-6TQ144I is obsolete per Xilinx documentation dated May 1999. However, Aetrix Electronics maintains traceable inventory of tested, original-packaged units sourced from authorized channels for legacy system sustainment and repair programs requiring genuine XC4004A-6TQ144I devices.
What configuration modes does XC4004A-6TQ144I support?
XC4004A-6TQ144I supports Master Serial, Slave Serial, and Master Parallel configuration modes. The 144-pin TQFP package exposes PROGRAM, INIT, CCLK, and DONE pins essential for all three methods. Master Parallel uses 18 address bits, limiting maximum PROM size to 256 KB for XC4004A-6TQ144I.
Can XC4004A-6TQ144I be used in 3.3 V systems?
No - XC4004A-6TQ144I is a 5 V-only device. Its I/O structure, internal voltage references, and configuration circuitry require VCC = 5.0 V ± 5%. For 3.3 V operation, Xilinx recommends the XC4004XL family, which features 5 V-tolerant I/Os but operates core logic at 3.3 V - XC4004A-6TQ144I cannot substitute without level translation.
Does XC4004A-6TQ144I support dual-port RAM functionality?
Yes - XC4004A-6TQ144I supports dual-port RAM mode in every CLB. When enabled, the 16×2 RAM resource becomes a 16×1 dual-port block with independent read and write ports, allowing simultaneous access - a capability confirmed in the XC4000E data sheet and applicable to XC4004A-6TQ144I as a member of that family.
What is the maximum operating temperature for XC4004A-6TQ144I?
XC4004A-6TQ144I is specified for industrial temperature range: –40 °C to +85 °C. This rating is documented in Xilinx's XC4000E family data sheet and applies to the -6 speed grade in TQFP packaging. Thermal derating is not required within this ambient range when mounted per JEDEC standards.
